A simple way to test a defective CPS that has temperature related faillure is to connect an ( Ω ) omhmeter to the CPS .When cold the Ω meter will show continuity, then, use an hair dryer and heat the boby of the CPS and at one point you will see the circuit to open . . . let it cool and the circuit will come back to life.

I was able many time to reproduce the open circuit condition when the original CPS of my XF went defective . This test will confirm the cause of the no start condition or a stall in the trafic when engine get hot egnough.
